SX3008F does not respond to DHCP requests
I have an SX3008F (hardware 1.20 or 1.6 depending on where you look) which is "fresh" in that I…
- …have updated to the latest firmware release (Build 20231011 Rel.42220).
- …have not done any interesting configuration. For example, the only VLAN is the default.
The switch is acting pretty much un-managed — as you would expect — except of course that it knows how to acquire an IP address for itself from a DHCP server and add an entry to its routing table using the gateway offered by that DHCP server.
The first thing I want is for the switch to serve DHCP, so I've enabled that and created a pool of private addresses.
Some aspects of the pool creation interface are unfamiliar to me — despite my having what I thought was a fairly good understanding of DHCP — so it's possible this is where I have erred.
I can see in the DHCP packet statistics that requests are coming in (presumably from the computer on which I am typing right now)… but no responses are going out.
I take this to mean that this isn't a matter of the responses going to the wrong place. They simply aren't going anywhere at all because they do not exist.
Furthermore, I don't see any way to send them anywhere in particular, so it's difficult to say where they should be allowed to go except perhaps "everywhere", and that clearly isn't happening either.
Any hints would be welcome.
